Pope Pelagius I

Pope Pelagius I (510-4 March 561) was Pope from 556 to 561, succeeding Pope Vigilius and preceding Pope John III.

Biography
Pelagius was born in 510 AD to a noble family of Romans, and his father John was a vicar of a civil diocese of Rome. Pelagius was elected Pope in 556 AD, the second pope during the rule of the Byzantine Empire's rule over the city. Pope Agapetus I made him the papal nuncio to Constantinople in the Byzantine Empire, and in 556 he succeeded Pope Vigilius. Pelagius built the Santi Apostoli basilica in Rome to commemorate Narses' victory over the Ostrogoths at the Battle of Taginae, but he gained some infamy for changing his opinion on reconciling factions of Christianity at Justinian I of Byzantium's demands. He died in 561 AD.
